Yoplait Light changing artificial sweeteners

The maker of Yoplait Light is hoping a sweetener change can help bring back customers.

General Mills Inc. said Wednesday it plans to remove aspartame from its popular reduced-calorie yogurt and instead use another artificial sweetener, sucralose. Aspartame is better known by the brand names NutraSweet and Equal, while sucralose is the sweetener used in Splenda.

"We know that some consumers have concerns about aspartame, so this is a positive transition," General Mills CEO Ken Powell said in a phone interview.

Although sucralose is also an artificial sweetener, Powell said it has greater acceptance among consumers.

The change comes as General Mills struggles to fix its Yoplait business, which has been upended by the popularity of Greek yogurt and the move toward ingredients people feel are natural.
